Here you see the firmware levels and types of your controller cards. You will also see the WWPN (port WWN) and the WWNN (Node WWN) of your controller. As each of the cards do only have one port, you will see only one WWPN per WWN.

To find out which devices can be reached by these controllers, use the remote-port option of fcinfo. You will have to give the port to be controlled as an argument to "-p":

You see through the port with the WWPN 2100001b321fe69b (which is on c5 which can be seen on the first fcinfo command output) three devices: two scsi volumes and one other target: This is the fiberchannel controller on another machine. The fcinfo command helped me very much to find out where I have a configuration error on my fibrechannel fabric.

Just as a side note: the last scsi device in the example above has the WWNN 200000d0231c50be. This is one of the paths which are constructing the virtual scsi_vhci device c6t600D0230006C1C4C0C50BE5BC9D49100d0mentioned in my entry about scsi_vhci (MPxIO) names.
